Variable

Variable
Variable Va"ri*a*ble, n. 1. That which is variable; that which varies, or is subject to change. [1913 Webster]

2. (Math.) A quantity which may increase or decrease; a quantity which admits of an infinite number of values in the same expression; a variable quantity; as, in the equation x^{2} - y^{2} = R^{2}, x and y are variables. [1913 Webster]

3. (Naut.) (a) A shifting wind, or one that varies in force. (b) pl. Those parts of the sea where a steady wind is not expected, especially the parts between the trade-wind belts. [1913 Webster]

{Independent variable} (Math.), that one of two or more variables, connected with each other in any way whatever, to which changes are supposed to be given at will. Thus, in the equation x^{2} - y^{2} = R^{2}, if arbitrary changes are supposed to be given to x, then x is the independent variable, and y is called a function of x. There may be two or more independent variables in an equation or problem. Cf. {Dependent variable}, under {Dependent}. [1913 Webster]
